Quick Answer
Pemmican can spoil due to rancid fat, off-smell, and slimy texture. Check for an oily sheen, a sour or unpleasant odor, or an unusual color. If you're unsure, taste a small amount to detect bitterness or a bad aftertaste.
Visual Inspection
When inspecting pemmican for spoilage, look for an oily sheen on the surface, indicating rancid fat. Check the color, which should remain a rich brown or creamy white. Avoid pemmican with an unusual color, such as a greenish or yellowish tint, which may indicate spoilage. If the pemmican has developed a slimy texture or appears to have separated into distinct layers, it’s likely spoiled.
Olfactory and Gustatory Testing
Smell the pemmican for a sour or unpleasant odor, which may indicate spoilage. If the smell is off, it’s best to err on the side of caution and discard the pemmican. When in doubt, taste a small amount to detect bitterness or a bad aftertaste. Rancid pemmican may have a bitter or metallic taste, while good pemmican should have a rich, nutty flavor.
Storage and Handling
To prevent pemmican spoilage, store it in airtight containers, such as glass jars or plastic containers with tight-fitting lids. Keep the pemmican in a cool, dry place, away from direct sunlight and heat sources. When handling pemmican, use clean utensils and avoid contamination with other foods or substances. Regularly inspect the pemmican for signs of spoilage, and consider making a new batch every 6-12 months to ensure optimal quality and safety.
